Solve for x. 5 x − 19 ≤ 1 OR − 4 x + 3 < − 6

k0ka [10]

$5x - 19 \leqslant 1$

change

$\leqslant \: to \: =$

given you

$5x - 19 = 1$

making x the subject by transferring the -19 to the right hand side of the equation

$5x = 19 + 1$

$5x = 20$

dividing through by 5

$\frac{5x}{5} = \frac{20}{5}$

$x = 4$

{ ${x:x \leqslant 4}$ }

also given

$- 4x + 3 < - 6$

change the operation sign to =

$- 4x + 3 = - 6$

$- 4x = - 6 - 3$

$- 4x = - 9$

dividing through by -4

$\frac{ - 4x}{ - 4} = \frac{ - 9}{ - 4}$

$x = \frac{9}{4}$

so the truth set is

{x:x>9/4}.

The < sign changes to > because we divided by a negative number when solving for x

3) Michael is getting dinner for his drama club on the evening of their final rehearsal.

bagirrra123 [75]

Answer:

5.5p + 5 ≤ 60

10 pounds

Step-by-step explanation:

a) The maximum total cost he can spend is $60.

5.5 * p + 2 * 2.5 ≤ 60

Simplify.

5.5p + 5 ≤ 60

b) Solve 5.5p + 5 ≤ 60

Subtract 5 from both sides

5.5p ≤ 55

Divide both sides by 5.5

p ≤ 10

So, the maximum he can buy is 10 pounds of food
